How do I find the current if the voltage is 6 volts, and there is no resistance?
I know how to find the current if there IS resistance, but I don't know how if there isn't any at all.

This circuit is on a piece of paper, I can't plug it in. It's asking me what is the current flowing past this point after the battery, which is 6 volts.

I=V/R
so R - > 0; I -> infinite
or R - > infinite ; I -> 0
This is it!

"This circuit is on a piece of paper, I can't plug it in. It's asking me what is the current flowing past this point after the battery, which is 6 volts."
Are there any other components involved?

If it is an ideal voltage source: no internal resistance, voltage independant of current out and it is across zero resistance, the current has to approach infinity. You have zero in the denominator. With the information you have provided that is the answer.

First plug it in.
